LOUVER.

`Application filedv February 20, 1926. 'Serial No. 89,809.

The present invention r'elate's to louvers :and .an object ofthe invention lis-'to provide a louver which may be economically fmanu factured. A further object of the invention is to provide alouver in which the slats may be adjusted to assume different angular positions with reference to their supporting up. rights.

To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described; the novel features being pointed out in the appended claims:

In the drawings: Fig. l is a horizontal section through the louver;

Fig. 2 is a fragmentary front view of the louver;

Fig. 3 is a fragmentary view of the louver partially in section showing the slats canted or inclined with reference to the uprights.

Fig. 4 is a section on the line 4.-4, Fig. 2; and

Fig. 5 is a section on the line 5 5, Fig. 2.

Referring more particularly to the drawings, 1 indicates the article in which the louver is mounted, such, for instance, as the door of a ship. The louver comprises an upper frame member Q provided with a groove 3 in its underside and having both its vertical faces covered by a molding 4. The frame also embodies the lower member 5 formed with a rib 6 on its upper surface and having its outer faces covered by molding 7 Connecting the upper and lower members of the frame are two frame pieces or uprights 8, which are preferably narrower than the pieces t and 5 and are covered on their outer faces by molding` 9 projecting beyond the frame pieces 8 to provide vertical grooves. In these grooves or recesses the supporting uprights 10 are arranged. These uprights are preferably formed from channel iron, the flange of the V channel being received between t-he projecting portions of the molding 9. These channel pieces form the vertical supports for the louver slats l1, which are also preferably formed from metal and are substantially inverted V in cross-section making them in channel form. These slats are arranged parallel and the top of each slat projects beyond the lowermost edge of the slat next above it so'that it is impossible to lobtain a line of vision between the slats, aslthough 'openings `or air passages `are provided.. The top of the upper sla'ft projects into the notch "3 Jinfth'e upper yedge of the *frame piece 2 `while the lower edges `off `the lower slat project below the upper edge of the projection or rib 6 on the lower frame piece 5.

The slats are so connected to the vertical supports or uprights 10, that upon the shiftiing of the uprights vertically, one relatively to the other, the slats will pivot or swing on the uprights so as to maintain their parallel relation while, at the same time, having an inclined or canted position as illustrated in Fig. 3 of the drawings. Such arrangement is desirable when the door or other structure in which the louver is to be arranged is canted, a condition often met with in the building of stateroom doors for ships. These pivotal connections between the slats and the upright supports are obtained, in this instance, by providing in the bottoms of the .channels of the uprights slots or openings 12, these slots receiving the slats and being formed identical in cross section with the cross section of the slats only having a slightly larger size. This arrangement makes it possible to secure the slats to the uprights without any fastening devices, permits the ready assembling of the louver, and also permits the canting of the louver.

It will be noted that applicants two upright rails are not rigidly connected except when placed in the outer wooden frame work. This permits the relative adjustment of the rails to incline the slats of the louver, the wooden frame work thereafter being built about the adjustable rails and slats. If the slats are of inverted V shape even though the plane of the louver is inclined to the vertical as in some structures, it is impossible to obtain a direct line of vision through the louver and yet at the same time the ingress or egress of air is possible. Furthermore, as both sides of the louver are alike, the latter is reversible.

What I claim as my invention and desire to secure by Letters Patent is:

l. A louver comprising two uprights, each formed with slots, slats connecting said uprights and projecting loosely into the slots, the ends of the. uprights being unconnected .l (il) changed, and a frame surrounding said slats and uprights and holding them in their adjusted positions.

2. A louver comprising two channeled uprights each formed with substantially inverted V shaped slots extending through the bottom of the channel, slats of substantially V in cross section connecting said uprights and projecting loosely through the slots, the

ends of the uprights being unconnected so thatk the angle of the slats may be changed, and a frame surrounding said slats and uprights and holding them in their adjusted positions.

3. A louver comprising two channeled uprghts each formed with substantially in- Verted V shaped slots extending through the Y bottom of the channel, slats of substantially V in cross section connecting said uprights and projecting loosely through the slots, the ends of the uprights being unconnected so that the angle of the slats may be changed, and a frame surrounding said slats and uprights and holding them in their adjust-ed positions, said frame having its upper bar formed with a groove opposite the projecting end into which the upper part of the upper slatprojects and having its lower bar formed with a rib projecting into the groove of the lower slat.
